I worked at a company where there were several women in the office. One of the women was 40 and decided to go back and try to finish her degree that was interrupted when she got married and had kids. During one break, she was complaining about the math and one of the ladies told her that I was a math major in college. She came to me, asking if I would mind tutoring her. She was still pretty nice looking and she begged for help, so I said sure. I went over to her house the next evening and we were going over some basic stuff, trying to bring her up to speed, and she decided to change into more comfortable clothes. She came back into the room wearing some loose shorts and a loose blouse. I could see her nipples peaking through the thin blouse and when she sat back down at the table, she dropped her hand into my lap and felt my hard. I reached under her shorts and not only no panties, but also pretty moist. We took a study break and fucked for an hour. We cleaned up a bit, we ordered a pizza and then worked on math a bit. Once the pizza got there, we enjoyed the pizza but also more playing around. We fucked again for about an hour and then got back to the math. She decided she needed instruction several times a week, depending on my schedule. Since she was a great fuck, I kept my calendar opened for quite a while.
